Whilst ripping out the rotten boot floor and heel board i realised that the little square filler/closing plate for the wheel arch to floor panel was rotten as well.
Is this available as a complete piece or does the little radius part of the plate have to be added after?
The radius is the inside of the beginning for the curve of the rear arch.


Any advice on where to get these or how you have tackled the problem would be greatly received.
Thanks
